To alt whom it may concern:

Be it knownthat I, VALENTIN ARANGURE Y BUSTINZA, citizen of the United States, re-

siding at New York, in the county of N ew York and State of New York, have invented certain new and useful Improvements in Paint-Machines, of which the following is a --spec1fication. Y

"This invention relates to that class of machines or apparatus that .are designed to apply paint, cal'cimine, or the like to walls, cei ings and other surfaces through the actionof compressed air which atomizes the fluid coloring material and applies it in the formof spray over'the surface to be coated in an even, manner and without any of the streaky effects that are so noticeable from the use of a brush and that are so hard to overcome.

The present invention has for its object a multi-eolor machine of this character which will be of comparatively simple, durable and efficient construction and which will be capable of applying two or more colors by the use of the same machine, all as will be hereinafter fully described and claimed.

For a full understanding of the invention reference is to be had to the accompanying drawings, in which: Flgure 1 1s asectional slde elevation of my improved paint mach ne; Fig. 2 IS a horizontal sectional View on the line 2'2 of Fig.

sectional view through the valve casing; Fig.

7 is a detail transverse section on the line '@/y' of Fig. 1; Fig. 8 is a detail view ,of the staff.

Corresponding and like parts are referred to in the followin description and indicated -in all the views 0 the drawings by the same reference characters.

My improved paint machine comprises a main tan 1,which together with its related parts is designed, when used, to be strapped to the back or the shoulders of .the operator,

and auxiliary tanks 2 and 3 which are mounted within the main tank 1 and which are preferably spaced therefrom on all sides.

. These tanks are designed to contain, re-

spectively, paints or other fluid coloring substances ofthe different colors. The aux1liary tanks 2 and 3 are provided respectively with filling tubes 4 which extend upwardlythrough the cover or lid of the tank 1, screw caps 5 or other closures being supplied to close the up er ends of the said filling-tubes, in an air tigl ft manner after the paints or the like have been poured in. 6 designates a similar filliny tube for the main tank. Manifestly, the l1(lS of the res ective tanks are secured thereto with an air tight joint.

Secured in any desired manner to the main tank 1 and preferably at opposite. sides thereof, are the air drums 7,,two in number in the present instance. A hand operated air uinp 8 is secured in operative relation to the drums 7 and is connected thereto by means of the pipes 9 that are preferably secured to the lower ends of the drums as shown. The drums 7 are connected to. the

pipes 10, each of said pipes being formed with a ranch 9* extending into the main tank 1, so that air may be forced into thetanks 1, 2 and 3 simultaneously. The air drums 7 are provided with the usual gagcs as shown,and the air pipes 10 are provided with shut-ol1' cocks; i

The several tanks 1, 2 and 3 are connected by distinct or separate tubes 11, preferably attached thereto at their lower ends, to a valve casing 12, which is provided withthrce distinct passages or ports covered by threedistinct cocks, 13, 14 and 15, the several tubes 11 communicating with the respective ports or passages. Flexible tubes or pipes 16, 17 and 18 preferably of rubber hose, are

attached at one end to the valve casing 12 and at the respective ports thereof, and are preferably contained within a sheath 19. The said shut-offs and the other ends of the tubes 16, 17 and 18 are attached to a hollow handle 20 also formed with three distinct passages and provided at one end with a valve casing 21 in Which three spring tension keys 22, 23, and 24 work, so as to control the flow of the paints or the like through the hollow handle out through the said-valve casing 21. A series of substantially rigid pipes 25, 26 and 27 are attached to one end of the handle 20 in communication with the three passages thereof, and the ports of the valve casing 21, said pipes being constructed in ilongitudinally extensible and telescoping sections,' so that they may be lengthened or shortened, as the case mayreq uire. A sleeve 28 is slipped over the'outerend of the pipes 175 auxiliary tanks 2 and 3 by means of the air 25, 26 and 27 and is preferably slidingly I air drums 7 preferably throu h the instru-' mentality of the pipes 9, so t at when the apparatus mounted thereon for-extensible movement, and three s ray nozzles 29 are detachably and adjustaiily held, preferably by frictional engagement, within the said sleeve, in communication with the respective pipes 25, 26

and 27. Each of the spray nozzles 29 is fan shaped as shown, and is provided with a flange 30 on which the wirescreen section 31 is adapted to fit, so as to finely divide the fluid coloringsubstanccs as they issue tromthe nozzles and evenly distribute it over the surface. to be coated. The said screen 31 is preferabl secured to the flange 30 by means of an arc ed shaped frame 32 secured to the flange bymeans of a clamping screw 33. It is of course to he understood-that the air drums 7 are charged by means of the hand )ump 8 before the operator starts to work. t is manifestly expedient to maintain a proper amount of compressed air within the drums, and to provide for the depletion of air supply during the operation of the apparatus, I preferably provide a motor actuated air pumung apparatus in connection with the hand pum 8. This air pumping referab y comprises two air pump cylim ers 34 and 35, mounted to oscilate upon standards 36 rising from the lid or cover of the main tank 1. The two piston rods 37 of the pump cylinders 34 and 35, are both connected by a wristpin or the .like, to the gear wheel 38 which is driven by the spring drum {SQ-mounted upon the main tank 1.

40 designates a handle by which the'motor may be wound u From the outlet ends of the respective cylinders 34 and 35 flexible tubes 41 lead. These tubes are connected to the respective motor is permitted to'operate, air willlxe forced into the drums.

Normally the spring motor is held at rest.

This is accomplis ed by means of a spring pressed locking pawl 42. In order to reease the Ipawl from engagement with the gear whee 38 and permit the motor to operate, I provide a flexible ull cord 44, which extends through the flexiolesheath 45 and down over the apparatus in convenient reach of one of the operator's hands. The outer end of the pull cord 44 is attached to a hellcrank 46provided at one end with a finger grip designed to coact with a relatively stationary finger grip 47 secured to the sheath 45 and'by pinching the two finger grips together the cord 44 will be c )erated and the pawl 42 disengaged from the gear wheel 38.

In the practical use of my improved multicolor painting machine, the drum 7 will of course first be supplied with compressed air and the apparatus will be strapped to the supplying sai operators back. -()ne hand, naturally the right hand,-will grasp the handle 20, leaving I 'the left hand free to manipulate the motor releasing means. If it be intended to apply only one color, two of the three cocks 13, 14 and 15 will be shut off. If, however, it be desired to apply a (plurality of colors to the.

surface to be coate one color at a time, the three cocks 13, 14 and 15 will be opened and the operator will depend entirely upon the three cocks, 22, 23 and 24, for hiscontrol of the passage of fluid out of the respective spray nozzles 29. By manipulating any one of these cocks, the fluid of the desired color will be permitted to issue from its nozzle in an evident manner, and one color may be substituted for another very quickly by simply manipulating the several spring cocks of the valvecasing 21 of the handle 20. As the pipes25, 26 and 27, which, together with the handle 20 comprises the color ap- )lying'staif of the apparatus, are extensilile, it is evident that the devices may be used with a comparatively high ceiling and with other places which are more or less inaccessible to the painter supplied with the ordinary appliances.
